Serial No. 148,281.

My invention relates to mechanism for controlling the feed of bristles or similar brush a materials to a base piece or holding strip to which said material is secured, the whole being intended for subsequent use in the making of brushes, and an object of my invention, among others, is the production of mechanism whereby the feed of material to a holding strip or base may be varied from a continuous even feed to an interrupted variable feed, whereby sections of difl'erent thickness of bristles may be obtained and whereby sections devoid of bristles, thereby providing spaces, are obtained and whereby the lengths of such sections and spaces may be varied to suit any special requirement.

One form of machine embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in rear elevation of a machine embodying my invention.

Figure 2 is a top View of the same with parts broken away to show construction, omitting the folding disc.

Figure 3 is an end view looking at the right hand end of the machine as seen in Figure 1.

Figure 4 is a detail view illustrating the construction and operation of the spacing mechanism.

or "d thereon at or near one end a table 6 from which a pedestal 7 rises, which pedestal comhopper 8 adapted to contain bristles or other brush making material, the construction and operation of which hopper, together with mcchanlsm for conveying the bristles therefrom is fully set forth and disclosed in my copending application filed February 16, 1926, of Serial Number 88,711.

A driving shaft supporting arm 9 is secured at its lower end to a rock shaft 10 mounted in brackets 11 attached to the table 6, a driving shaft 12 being mounted in a caring in the upper end of the arm and having a driving pulley 13 adapted to receive a driving belt 14 extending to any suitable source of power. The shaft 12 has driving discs 15 attached thereto, the peripheries of said discs projecting into spaces between clutch discs 16 secured to a feed shaft 17 in a manner to move lengthwise of said shaft to a slight extent but to rotate said shaft, one member 18 of said clutch discs being engaged by a forked clutch actuating lever 19 to be hereinafter described. Said discs 2'" are forced apart or disengaged in any suitable manner, manually or mechanically.

A feed disc 20 is secured to the shaft 17 and is provided with notches 21 in its periphery that projects into the lower end of the hopper 8 and by means of which bristles or other brush material is, in the rotation of said disc, taken from the hopper and deposited upon feed belts 2223 arranged preferably in pairs, one pair being located above the other and the brush material being carried between them. Said belts are mounted at their opposite ends upon rolls supported in any suitable manner, the belts 23 being driven by frictional contact with the brush material or with the belts 22 when there is no material between the belts. The rolls 24 for supporting one end of each of the belts 22 are each rotatably mounted on the upper end of an arm 25, the lower-end of which is pivotally adjustably secured to the bracket 11. A shaft 26 supporting the rolls for the belts 22 is rotatably mounted in the bracket 11, said rolls being secured to said shaft, and the latter being driven as by means of a gear 27 secured to the shaft and meshing with a gear, not shown, forming a part of the mechanism of the machine.

The parts thus far described form the subect matter of my copending application hereinbefore referred to and for WhlCh reason a general description only is given herein, a specific and detailed description not being necessary for a complete understanding of the invention, and said copending application being referred to for any further description that may be desired.

Said machine in its general construction further embodies means for feeding a strip or holding piece 28 having a groove into which the bristles 29 are forced by bending or folding, as by the action of a folding disc 30 rotatably mounted and from which the strip with said bristles folded therein is passed between pressing rolls 31, as more particularly set forth and claimed in my copending application filed December 14, 1925, of Serial Number 75,219, and to which reference is hereby made for a more complete understanding, if desired. The disc 30 conducts a wire 94 into the fold of the bristles as an aid in retaining them in the strip 28.

My improved machine is intended for the formation of brush strips of indefinite lengths, which strips are cut into suitable lengths by mechanism which may or may not comprise a part of the machine as a whole. In the construction of many brushes it is desired that the end or ends of the brush lengths 32 cut from the strip 33 shall be free from brush material forvarious reasons, as for the reception within a handle 34 of a 3 brush, as shown in Figure 7. Therefore, my

improved machine is provided with means for automatically creating spaces 35 in the formation of the strip 33.

It is also desirable in some cases to provide thick sections 36 at more or less regular intervals in the formation of the strip 33, such thick sections, as one instance of use, providing a thickened end 37 in a brush 38, and as shown in Figure 7. My improved machine is therefore provided with means for autothe formation of the brush strips, said mechanism controlling the feed of brush material to the strip 28 and including a driving pulley 39 secured to a driving shaft 40 mounted in hearings in brackets on the base 5, said shaft having a pinion 41 meshing with a gear 42 mounted on said base, the shaft of said gear being connected by mechanism (not herein shown) to drive other mechanisms including the pressing rolls 31, knowledge of said connection not being necessary for a thorough understanding of the present invention, but which connection is shown in my hereinbefore mentioned copending application S. No. 75,219, and to which reference is hereby again made for such further understanding as may be desired.

The mechanism just hereinbefore de scribed is a controller mechanism for which controller driving mechanism is provided, such driving mechanism including a gear 42 meshing with a pinion 43 secured to a clutch driving shaft 44 mounted in bearings in brackets secured to the base 5 and having clutch discs 45 loosely secured thereto to rotate therewith but havin a slight endwise movement thereon as do t e discs 15 hereinbefore mentioned, said discs 45 projecting Y into the spaces between clutch discs 46 loosely supported by a clutch shaft 47 but engaged with said shaft to rotate it, said discs 46 being spring pressed toward each other in a manner well known in structures of this kind, and as shown in dotted lines in Figure 1. One of the outside discs-46 has a grooved clutch actuating collar 48 for engagement with one arm of a clutch actuating lever 49 pivotally mounted on the end of an arm 50 extending from one end of a bracket 51 secured to the base 5.

The controller mechanism embodies mechanism for determining the len h of the brush sections and this includes t e shaft 47 mounted in hearings on a swinging support 52, the lower end of which is pivotally attached to a feed controlling shaft 53 mounted in the arm '50 and in an arm 54 projecting from the bracket 51. The upper end of the support 52 has a block 55 pivotally attached thereto and having a threaded hole engaged by a screw threaded adjusting rod 56 extending through and rotatably mounted in a supporting block 57 pivotally attached to a supporting bracket 58 secured to a post 59 rising from the base 5 and secured thereto at its lower end, as by means of a nut, as shown in Figure 3 of the drawings. An adjusting hand wheel 60 secured to the end of the rod 56 is employed for rotating the latter, this end of said rod being secured against independent movement lengthwise of the block 57 but being freely rotatable therein whereby rotation of the hand wheel causes the support 52 to swing on its pivot for the purmatically accomphshmg these purposes in pose of adjusting the relative positions of the discs 45 and 46 and thereby varying the speed of rotation of the shaft 47 A telescoping indicating rod 61 is secured to the blocks 55 and 57, the outer section of the rod having an opening for view of graduations 95 on the other section, and the engagement of the rod sect-ions being loose enough if need be to permit the necessar swinging movement of the blocks in the ad ustment of the support 52.

The controller mechanism further embodies spacing mechanism that includes the shaft 47 having a pinion 62 meshing with a ear 63 secured to' the controlling shaft 53, w lereby the latter is rotated for the purpose of op erating the mechanisms for controlling the length of the spaces 35 relatively to the portions 29 and 36 and thereby determining the relative lengths of the portions 29 and 36 of the brush strip. To accomplish this purpose the feed of the bristles by the disc 20 is interrupted at intervals after which the feed again takes place and this is effected by operation of the clutch discs 15 and 16 by means of feed controlling pins 64-65 projecting from discs 66 secured to and resting against opposite sides of the gear 63, said pins being positioned to engage feed controlling fingers 67-68 secured to and projecting from a feed controlling sleeve 69 mounted for rocking movement on a shaft secured in the arm 54 and an extension 70 from the bracket 51. The finger 68 is connected by a link 71 with an arm 72 projecting from a rock shaft 73 mounted at opposite ends in the arm 54 and in a bracket 74 secured to the bed 5. The end of the shaft opposite the arm 72 has a toe 75 in engagement with an arm 76 of the actuating lever 19. The pins 64 and 65 are adjustably mounted in slots in the discs 66, as shown in Figures 3 and 4, and by properly positioning these ins the time of their engagement with the ngers 67 and 68 to secure and release the clutch discs 15 and 16 may be regulated to obtain such widths of the spaces 35 as may be desired.

Engagement of the pin 65 with the finger 68 rocks the shaft 73 and moves the toe 75 to a position to act upon the lever 19 and force the discs 16 apart against the tension of their spring, which spring may be arranged in a manner similar to that shown in dotted lines within-the collar 48 in Figure 1, and the movement of the sleeve 69 may be effected by a spring 77. A handle 98 is secured to the lever 19 for manual actuation thereof when desired. The finger 68, when moved by the pin 65 to its lowest position, will locate the pivotal point of attachment of the link 71 to said finger just beyond a line passing through the centers of the shaft 81 on Which said finger is mounted and the pivot connecting said link to the arm 72, whereby the finger will remain in this position until the pin 64 engagin; the finger 67 moves said pivotal point back to the opposite side of said line, at which time the spring 77 will snap the finger 67 to its opposite position and as shown in Figure 3 of the drawings. This operation releases the toe 75 from the arm 76 permitting the spring for the discs 16 to force the discs 15 and 16 into driving contact.

From the foregoing description it will be seen that bv manual operation of the hand wheel 60 the discs 45-46 may be adjusted for engagement in a'manner to lengthen or shorten the brush lengths 32, and by adjusting the position of the pins 64-65 the width of the spaces 35 may be determined.

The controller mechanism further embodies tufting mechanism for producing the thick sections or tufts 36, this being done by manipulation of the discs 15-16 to swing them towardor from each other, said tufting mechanism including a rocker rod 78 extending through the arm 9, with a spring 79 at one end for rocking the arm in one direction and a rocker lever 80 connected with the opposite end of said arm to rock it in the opposite direction, the lever 80 being secured to a sleeve mounted on a shaft 81 on which the sleeve 69 is mounted. This lever 80 has a roller in contact with a cam secured to the shaft 53 and comprising two members 82-83 adjustably connected and the latter havin a collar 84 loosely fitting the shaft 53. he member 82 loosely fits upon the shaft 53 and is secured to said shaft as by means of a hook 90 secured at one end to said member as by means of a nut that draws the opposite and hooked end into tight contact with a collar 91 secured to the shaft 53. When this cam engages the arm 9 is rocked to move the discs 15-16 apart, thus increasing the rate of rotation of the feed disc 20 and thereby producing the thickened sections 36, and the length of these thickened sections will depend on the width of the cam comprising the combined length of the ends of the members 82-83 as determined by the relative positions of said members. By varying the relative positions of the cam members 82-83 the lengths of the tufts 36 may be varied as desired.

If it be desired to produce a strip with the bristles continuous and of even thickness the lever 49 may be rocked by operation of an eccentric pin 85 on a clutch disconnecting shaft 86 mounted at one end in the arm 50 and at its opposite end in a bearing 92 secured to the base 5 and as shown in Figure l of the drawings. A handle 93 projects from the shaft 86 as a means for manually operating it.

The relative positions of the discs 15 and 16 are adjusted to vary the speed of the disc 20 and thereby obtain the desired thickness of the thin portions 29 of the bristles by an adjusting screw 87 threadedly fitting in the table 6 and having an adjustable stop 88 against which a lever 89 rests, said lever being secured to the shaft 10 and being held against said stop by the spring 79. The posi' tion of the stop 88 will determine the thicklever 80 the ness of the thin portion of the bristles and by changing the position of this stop by turning the screw out or in such thickness may be varied at will. It may be noted that this adjustment will not change the thickness of the thick section 36 of the strip for the reason that the adjustment slackens the flexible connection 96, which slack is immediately taken up when the cam (82-83) engages the lever 80. However, the thickness of the thick section 36 may be correspondingly increased by taking up the slack of the chain or flexible connection by means of an adjustable connection 97 shown in Figure 1.

The controlling mechanism hereinbefore described and comprising the members borne by the shaft 53 and also connected therewith for operation thereof and to be operated thereby, is for the purpose of effecting the formation of brush strips as shown m Fig ure 6, each cycle of movement of such controlling mechanism, that comprises a complete rotation of the shaft 53, being effective to produce such a strip. If the speed of this controlling mechanism be varied without changing the rate of travel of the holding strip 28 the length of the brush lengths 32 will be accordingly varied. This change in speed of controlling mechanism is obtained bychanging the length of the indicating rod 61 as by means of the hand wheel 60 screw- ,ing the rod 56 into the block 55, the graduations on the rod 61 indicating the length of the strip to be produced in this operation.

After the length of the strip has been determined by means of said indicating rod the relative lengths of the brush sectlons and of the spaces between them may be fixed by means ofthe pins 64-65. By locating the pins nearer together in the direction of the least space between them, as shown in Flgures 3 and 4, the length of the space 35 will be decreased and the lengths of the combined brush sections 29 and 36 will be increased.

The length of the combined brush sections 29 and 36 having been thus determinedthe positions of the sections 36 in the sections 29 may be fixed by adjusting the position of the cams 8283 on the shaft 53, thereby de termining the time of operation of the lever 19 to operate the discs 15-16 to increase or decrease the speed of the disc 20 to increase or decrease the thickness of the bristles, as at 36, and the relative positions of the cams 8283 may be changed to increase or decrease the length of the operating edge of said combined cams to increase or decrease the length of time of speeding up of the disc 20 to increase or decrease the length of the brush sections 36, which increase in length of said sections 36 will decrease the length of the brush sections 29. v

In the mechanism hereinbefore described the bristles are fed to the holding strip 28 substantially at their lengthwise centers, whereby both ends of the bristles project to substantially the same extent and both the butts and flags? of the bristles, therefore, comprise the edge of the brush. The flags, which are the tlps of the bristles, are finer than the butts, and it is, therefore, desirable in some instances to produce a brush of extremely soft construction and com sed entirely of the flags or tips of the bristles. This may be done by arranging the bristles with the tips all extending in one direction and by placing the bristles between the belts 22-23 with the butts located over the holding strip 28. In this disposition the butts of the bristles are tucked into the holding strip as shown in Figure 9, and the flags or .tips

of the bristles comprise the end of the brush.
